PDF Combiner

Help

Usage

Click "Add File" then use the file browser to select one or more PDF files. Rearrange them, change the start and end pages, duplicate or remove them in the file list area. Modify the quality if you wish. The quality will have a large effect on the output file size and processing time. I recommend 120 DPI for a good balance. Click "Combine" to produce the output PDF - your browser will automatically download the result.

Offline Usage

Download the following files, keep them in the same folder, then open index.html:

index.html
libmupdf.js
libmupdf.wasm
magick.js
magickApi.js
magick.wasm

Privacy

Aside from the files packaged with this HTML document, this tool requires no external resources and makes no external requests. Therefore, it can make no invasion on your privacy. You may verify these statements by using your browser's developer utilities to view network traffic - you will see that only the packaged files are loaded and no further requests occur. You may also verify these statements by using the tool entirely in offline mode, or disconnected from the Internet. It will work fully.
